RF to video adapter

Postby drepouille » Thu Mar 13, 2014 2:05 pm

During stake conference, I have for years used an old VCR to convert RF channel 4 to a video signal for the projector in the cultural hall. Well, that VCR died. I had to unmount another VCR from a TV cart temporarily for last week's stake conference.

What device can I purchase to convert RF channel 4 to a video RCA plug without using a VCR tuner?

I wonder if any of those HDTV tuners that were designed to allow receiving digital TV with older sets can tune analog signals? I know that many of them have the composite outputs.

You might also talk with FM about adding a baseband connection to the cultural hall.

You could use a tuner box like this. I haven't used that item personally, but it gives you the idea.

If it is possible to switch from RF to regular composite video, it would be much better.

This is what I did in our cultural hall. The RF connection was a 'home run' (one cable from the satellite cabinet to the jack) with no splitters or taps - just a single wire. I simply added an adapter in the cabinet to make the connection a BNC and plugged it into one of the open connections on the video distribution amplifier, then I switched out the wall plate for an RCA connector. Finally I got a long RCA cable for our projector.

Now we never have to find and connect a VCR, nor do we need to tune the VCR to the correct channel and the picture is superior to what we had before.

Check to see if you can do the same - it will save a lot of hassle. PM me if you need additional instructions.

Our FM group had this done this for us in our stake center during the last round of upgrades. Both the cultural hall and chapel have wall-mounted RCA jacks carrying composite video that's linked to the output of the satellite receiver. This makes setting up 2 projectors for general conference (or a regional stake conference) a breeze.

Problem is, during a local stake conference when we input a video feed into the camera jack in the back of the chapel, it doesn't come out on the composite jack in the cultural hall. That jack is set to only show what's coming over the satellite. For those cases, we still keep a VCR on hand. I know I could rewire the satellite cabinet each time, but a VCR works.

Flexibility is the key. We need to show video from the camera jack in the overflow. We also need the ability to show English on channel 4, Spanish on channel 5, and ASL on channel 6. So I think the RF cable jack in the cultural hall is fine. I just need a portable tuner to convert the desired channel into composite video.

russellhltn has the right idea. Talk to the FM manger, and he can order a tuner to replace the VCR.
A note of caution: most of the standalone tuners currently available are not the best quality, but it should hold you over till the building comes due for a system update, which will eliminate the need for a TV tuner.

I'm not sure I understand. I can't see any need for an RF channel (TV) in the cultural hall.

Speaking strictly of the cultural hall audio overflow: when the doors between the cultural hall and chapel are open, isn't the sound in the cultural hall always the same as the chapel?

If a different audio language was needed for only the cultural hall, the picture would be the same (excluding ASL) but that audio would compete with the chapel's. In addition, for sound in the cultural hall to be different from the chapel, the overflow sound would need to be disabled. How would you get the other language to come through the speakers...(I'm lost)?

...I could never imagine a set up with a different language heard in the cultural hall. ASL perhaps, but that's only video, so a better picture could still be obtained via rewiring the RF jack to a composite video connection.

In our building, there is a switch to select the distributed feed (Satellite, VCR/DVD, Camera or other). The only advantage of the RF jacks in the building is the ability to listen to a different audio language.

I want one! Is your switch installed inside or outside the satellite cabinet (or somewhere else)?
